The first patch release (released on launch day) says: "Messaging to distinguish particular users hitting their user quota limit from all users hitting the global capacity limits." So, collectively we're hitting the quota, its not just your quota. (One would think Google might know how to scale their services on launch day...)
The Documentation (https://antigravity.google/docs/plans) claims that "Our modeling suggests that a very small fraction of power users will ever hit the per-five-hour rate limit, so our hope is that this is something that you won't have to worry about, and you feel unrestrained in your usage of Antigravity."
With Ultra I hit that limit in 20 minutes with Gemini 3 low. When the rate limit cleared some hours later, I got one prompt before hitting limit again.
If by "Ultra", you're referring to the Google AI Ultra plan, then I just want to let you know that it doesn't actually take Google AI plans into consideration. It seems like the product will have its own separate subscription. At the moment, everyone is on the same free plan until they finalize their subscription pricing/model (https://antigravity.google/docs/plans).
On a separate note, I think the UX is excellent and the output I've been getting so far are really good. It really does feel like AI-native development. I know asking for a more integrated issue-tracking experience might be expanding the scope too much but that's really the biggest missing feature right now. That and, I don't like the fact that the "Review Changes" doesn't work if you're asking it to modify reports that are not in the current workspace that's open.
you'd hope so, the same way you'd hope that AI IDEs would not show these package/dependency folder contents when referencing files using @ - but i still get shown a bunch of shit that i would never need to reference by hand
One would think this would have been obvious when it fails on the first or second request already, yet people here all complain about rate limits.
When I downloaded it, it already came with the proper "Failed due to model provider overload" message.
When it did work, the agent seemed great, achieving the intended changes in a React and python project. Particularly the web app looks much better than what Claude produced.
I did not see functionality to have it test the app in the browser yet.
